Dissolved cadmium (Cd) concentrations in water
in parts per billion (ppb) at 24 RMP stations sampled
in January, April, and August 1997. Concentrations
ranged from 0.003 to 0.15 ppb. The highest concentration
was sampled at Petaluma River (BD15) in August and
the lowest at Honker Bay (BF40) in January. Average
concentrations were highest (0.10 ppb) in the South
Bay in August and lowest (0.01 ppb) in the Rivers
in January. All samples were below the 4-day average
WQC for dissolved cadmium (saltwater 9.3 ppb, freshwater--hardness
dependent). |
